Answer 2

Oie, Td Bom?!

a)

x - 5° + 2x - 10° + 2x - 5° + 2x + 5° = 90°

x + 2x - 10° + 2x - 5° + 2x = 90°

7x - 10° - 5° = 90°

7x - 15° = 90°

7x = 90° + 15°

7x = 105°

x = 105°/7

x = 15°

b)

x/3 + x/2 = 90°

6(x/3 + x/2) = 6 . 90°

6 . x/3 + 6 . x/2 = 6 . 90°

2x + 3x = 6 . 90°

5x = 540°

x = 540°/5

x = 108°
